Abstract
A method of operating a toilet includes: (1) providing a toilet including: (a) a bowl; (b) a tank having first and second flush modes, wherein a first volume of water is flushed from the tank to the bowl in the first flush mode, and wherein a second volume of water greater than the first volume of water is flushed from the tank to the bowl in the second flush mode; (c) a flush mode mechanism for selecting between the first and second flush modes of the tank, wherein the flush mode mechanism is biased toward selecting the first flush mode; (2) optionally actuating the flush mode mechanism to select the second flush mode; and (3) flushing either the first volume of water or the second volume of water from the tank to the bowl responsive to the selected flush mode.
